“They have a very specific plan about the number of seasons they want to do,” Bloys told Entertainment Weekly. “If I could get them to do more, I would take 10 more seasons. But we take their lead on what they think they can do the best version of the show.”

Benioff and Weiss are due to start shooting season seven shortly. It will feature seven episodes, three fewer than previous seasons, and will debut on HBO in summer 2017. The eighth and final season is expected to follow in 2018.
